KATHMANDU, Nov 3: The festival of lights ‘Tihar’ has officially begun with Kaag and Kukur Tihar already celebrated on Wednesday. As the people are busy buying goods that are needed for the celebrations, the sale of electric decorative lights is also high across the country. It is believed that Laxmi, the Goddess of Wealth, visits the homes of those who keep their home well-lit and clean during Tihar. Due to this belief, people illuminate their homes with electric lights and butter lamps to invite the goddess to their homes.
